Application filed ilay 23, 1918.

To all whom, it may o 120cm: lie it known that I, Janus M. Gnrnn,citizen of the United States, residing at 2M9 rlarrison street, in thecity Chicago, and State of illinois, have invented ccrta new 'Hl nseiulimprovements in l'Ton- ..d chments tor AutomobiloTires, or which thefollowing is a specification. I My invention skid attachments has forits objects, skid attachment which quicl-zlv put on or s to removablenonautomobile tires, and 1 e providing of nonmay be easily and takenwithout the use of ra tools; one which is securely locked place whenonce adjusted against accio ital removal or loss; one which is low incost; one which produces very slight wear on the tire; one in whichbreaks may e easily, cheaply and quickly repaired; one which hassuincicnt play to shake lose any dirt or matter which may lodge in it;and one which has no angles or pockets where dirt or snow or icemaypermanently lodge to the detriment of its ciiiciency.

ll ith the above and other objects in view, my invention consists of thenovel construction, combination and arrangement of parts as are morefully illustrated and described in the accompanying drawings andspecifications hereunto appended.

in the annexed drawings, in which like numerals of reference refer tosimilar parts,

Figure l is a fragmentary elevation of an automobile wheel illustratingthe present invention applied thereto.

Fig. 2 is an enlarged plan view of one of the non-skid blocks employedby me.

Fig. 3 is a section view of the non-skid block shown in Fig. 2 takenalong the line Fig. 4: is a section view of the non-skid block shown inFig. 2 taken along the line 6-1).

In illustrating my said invention, 1 have shown a portion of the rim 1or" an automobe of any usual construction, having the tire 2 attachedthereto in any of the customary methods. As shown, my non-skidattachment. consists of a number of non-skid blocks 3, having a circularbody portion 4 bearing against the a tire, the inner surface or which isconcave, as at 5, with the elges rounded. as at 6 in order to reduce thewear caused by contact Specification of Letters Patent. 1

with the tire to the le: st possible minimum. Er rib "7 extends thelength trier-eel which designed to secure the greatest grin upon theroadvmy, to prevent T or skid-- ding.

These ribs '7 extend beyond the a of the body portion i, and in each endthereof have the holes 8 adapted to receive the rings 9 which connectthe non-skid blocks together into a continuous string oi e desiredlength. rrt one end of said s of non-skid blocks 1 have preierablyattached a larger ring, as 19. fit the reverse end of said string ofnon-skid blocks, 1 have prei erably attached a snap hook. at ll, whicais adapted to snap into the ring 10 or any other ring of said string ofnon-skid blocks and rings lesired in order to attach said string ofnon-skid blocks upon said tire against accidental detachment or loss.Where the ribs T join the body ii, as at 12, T

have provided fillets, in order to eliminate the possibility ct dirt,snow or ice collecting on said non-skid blocks, and diminishtheireffectiveness in gripping the roadway.

The chain-like device is provided at one end with ring 10 and theopposite end is provided with a snap hook 11. The method of attachingthe chain-like device is to first pass the end provided with the ring 10between the spokes of the wheel. The end having the snap hook 11 is thenpassed through the ring and the chain-like device pulled upon, forming aslip knot about the ring and tire. The chain is then wound about the rimand tire until the end having the snap hook 11 is brought into proximityto the ring 10 and snapped into engagement with the latter. If thechainlike device should be too long or too short to provide for aneffective connection between the ring 10 and snap hook 11, the snap hookcould be caught into some link of the chain-like device in proximity tothe ring 10. To remove the device, the snap hook is released from thering 10, and the device is unwound from thetire, and removed from thering 10. While I have described what I consider the simplest and mosteffective manner of attaching my device to a tire, it is apparent thatit is possible to attach it in many other ways, which may appear to theowner to be fully as effective as that illustrated.

hen attached to the tire, as explained above, my device forms acontinuous row with y will be rmgs are ofreasonably fair sized therebyof my non-skid blocks about the tire, with the ribs in contact with theroadway. As the blocks are concaved there is little or no Wear on thetire, and at the same time they'have a large bearing sur face upon saidtire. As the rings 9 all lie flatly against the tire,they present nosharp or raised projections to wear the tire, as with ordinary chains,and in addition, have a large bearing surface against the tire, insuringadditional gripping surface both against the roadway and the tire. Asthese diameter, they present little opportunity for dirt or snow or iceto lodge in them, and if it should find lodgment, the vibration of therings against the tire, as the .wheel rotates, would loosen such matter,and it would fall out. Ihave also, as will beseen, provided filletswhere the ribs adjoin the body of the blocks, preventing lodgment of anydirt or ice or snow in the angles thereformed, as might occur, deeplyrecessed.

Y I y constructing my'said non-skid blocks forming dies, or by castingthem, it apparent that they can be produced gain, in case of breakageofa ring, or block, such ring or block 7 may be easily, and quicklyremoved without special tools, and either another put in its on theinner surfaces,

' adapted onally of the tread of the tire place, or the remaining ringsand blocks connected making the devlce as usable as before. hlle I haveshown my device with Having thus described my said invention,

what I claim, and desire to secure by Letters Patent, is the following:

A non-skid chain for motor vehicle wheels to be spirally wrapped aroundthe tire and rim ing an inner face to fit the tire Y at its outer facewith a rib extending longitudinally of the chain and disposed diagwhenthe chain is 1n position thereon, said ribs being extended beyond thebody and ings, and connecting links passing through the openings of theribs.

In testimony whereof, I have hereunto set my hand in the presence of twosubscribing witnesses.
